Abstract

Waduk Dolok direncanakan dibangun dengan kapasitas tampungan 34,09 juta m3, tujuannya untuk memenuhi kebutuhan air irigasi dan air baku. Supaya tidak terjadi konflik kepentingan dalam pemanfaatan air maka perlu pengoperasian waduk yang optimal. Penelitian ini bertujuan untuk menyusun pola operasi waduk yang optimal menggunakan program dinamik dengan bantuan software CSUDP. Data inflow, kebutuhan air, evaporasi, faktor pembatas dan diskritisasi diperlukan untuk input program. Keluaran program berupa tahapan, tampungan waduk, pelepasan, dan fungsi tujuan. Rule curve hasil optimasi berada pada zona normal, sehingga rule curve ini bisa dijadikan dasar pengoperasian Waduk Dolok. Waduk Dolok mampu memenuhi kebutuhan air irigasi seluas 1.296 ha, sedangkan sisanya untuk kebutuhan air baku dan pemeliharaan sungai.

Abstract

The Wonogiri Reservoir capacity decreases rapidly, caused by serious sedimentation problems. In 2007, JICA was proposed a sediment storage reservoir with a new spillway for the purpose of sediment flushing / sluicing from The Keduang River. Due to the change of reservoir storage and change of reservoir system, it requires a sustainable reservoir operation technique. This technique is aimed to minimize the deviation between the input and output of sediments. The main objective of this study is to explore the optimal Wonogiri reservoir operation by minimizing the sediment trap. The CSUDP incremental dynamic programming procedure is used for the model optimization.  This new operating rules will also simulate a five years operation period, to show the effect of the implemented techniques. The result of the study are the newly developed reservoir operation system has many advantages when compared to the actual operation system and the disadvantage of this developed system is that the use is mainly designed for a wet hydrologic year, since its performance for the water supply is lower than the actual reservoir operations.Doi: 10.12777/ijse.6.1.16-23 [How to cite this article:  Wulandari, D.A., Legono, D., and Darsono, S., 2014.
